Late last August Christina Aguilera welcomed a beautiful baby girl into the world, and now after months of waiting, we've finally got our first glimpse of her daughter Summer Rain.

"Watch out...another one's getting ready to conquer the world! #driven #diva2," Aguilera captioned the cute Instagram picture.

Summer is the second child for Christina—who had her seven-year-old son Max with ex-husband Jordan Bratman, but Summer is her first child with fiancé Matthew Rutler. Christina infamously posed naked while pregnant with Summer for V magazine, and also headed into the recording studio while enormously pregnant for a cute baby bump moment.

Now that Summer is out and about we can't wait to see more mommy-daughter moments!
